The novel distortion matrix approach enables detection of micro-calcifications in breast cancer. These precursors of breast cancer are impossible to detect in the conventional ultrasound image.

The attenuation of low-frequency sound has been a challenging task because the dynamics of dissipative systems are generally governed by the rules of linear response, which dictate the frictional ...

Researchers have constructed a 'meta-mirror' device capable of perfectly reflecting sound waves in any direction. The proof-of-principle demonstration is analogous to looking directly into a mirror ...

THE author, who already, by a series of interesting treatises belonging to different branches of mathematical physics, has acquired a respected name in the domain of science, undertakes to give a ...

Taking pictures of the inside of the human body is something that we take for granted. But really, most current imaging systems are less than ideal. When it comes to getting the details without ...

Metamaterials researchers have created a thin plastic structure with geometric details allowing it to control the redirection and reflection of sound waves with almost perfect efficiency.

Stealthy flier: the Antheraea pernyi moth is very good at absorbing ultrasound. (Courtesy: University of Bristol) When moth wings are used to coat hard, artificial surfaces, they can significantly ...

In the guest blog, physicist Andrea Navarro-Quezada shows the importance of sound waves for our everyday life and research. Almost all of us know the concept of a wave. It is a periodic motion or ...
